DRY CLOSET.

SPECIFICATION forming part of Letters Patent No. 358,546, dated March 1, 1887.

' Application filed Septemher23, 1886. Serial No. M4341. (No model.)

To aZZ whojm it may concern:

Be it known that I, EZEKIEL G. CoNDrr, of Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in -Dry Closets, of which the following. is a specification.

My invention relates to dry closets of that class described in Patent to I. D. Smead, No. 314,884; and theinvention consisisin certaininr provements, hereinafter more fully described.

Figure 1 is a transversehorizontal section of a portion of a building, showing the closet with my improvements applied thereto. Fig. 2 is a longitudinal vertical section on the linewx of Fig. 1, and Fig. 3 is a transverse vertical section on the line 1 y of Fig. 2.

The object of my present invention is to pro vide means for applying a greater degree of heat to the deposits inthe vault, and to cause the hot air to travel a greater distance in the vault than can be when the apparatus is -constructed on the plan shown in the patent referred to.

In the accompanying drawings,B represents a portion of the wall of thebuilding, and R represents the ventilating-shaft, which extends from the basement out through the roof in the usual manner. The floor of the closets is represented by the letter and 0 indicates the covers of the seats, the vault 0 being directly underneath the same, as in the former case.

In the drawings I have shown the closets with their vaults as being built a short distance 'from the wall B, as I sometimes find it desirable, though in cases where it is more convenient they may be built up against the wall B, their location depending on circumstances as, for instance, whether the dry closet is to be applied to a building already erected, or is to be put in when the building is being built, my improvements being applicable in either case.

In the patent before referred to the vault was supplied with air drawn from the various rooms of the building, and which of course was somewhat reduced in temperature by the-time it entered the vault,through which it was drawn direct to the ventilating-shaft, the air passing but once through the vault and in one direction only.

As shown in Figs. 1 and2, I take the air for the vault directly from the exterior of the building through an opening, K, provided for that purpose; and in asuitable chamber at that end of the vault I locate a'furnaceorhcatenA, by which the air is heated to any degree desired. \Vithin the vault 0,1 locate a metallic partition or plate, L, as shown, whereby the vault is divided into two parts or ducts, (I and d, the one over the other, as shown in Figs. 2 and 3, the plate L being directly under the seats, so the deposits will fall thereon and be retained on said plate. This plateLis enough shorter than the vault to leave at the end farthest from the heaterAan opening, I,as shown in Figs. land 2, for the passage of the airfrom the lower duct, d, up into the duct (1, as indi cated by the arrows in Fig. 2. At the end nearest the heater A the upper duct, (1, is closed by a plate or partition, 0, as shown in Fig. 2, and at that end this duct d is connected with the ventilating-shaft R by a pipe, e,- or if the vault be built directly against the wall B, so as to abut against the shaft B, it may simply open into the shaft without any pipe, the only requisite in that particular being that it shall be so connected to the shaft R as to insure the passage of the air from the duct cl into the ventilating-shaft. This ventilating-shaft is always provided with means for heating it sufficiently to rarefy the air therein, and thus insure agood upward draft. In this caseIhave shown a smoke-flue, T, built up alongside of the ventilating-shaft, into which the smoke from. the heater A is conducted by a pipe, S, as shown in Fig. 1,the heat from which answers this purpose, though any other method may be adopted, if preferred, this, however, being the most convenient, inasmuch as there must be a flue for carrying away the smoke and gases of the heater or furnace A.

At the end of the vault farthest from the heater I provide an opening with a door,K,as shown in Figs. 1 and 2, to afford access to the vault for the removal of the dried deposits, when required, this door, however, being kept closed at all other times.

I would remark that the plate L may be provided with perforations sufficient to permit whatever liquid matter there may be to drain through and fall upon sand, it, or other absorbent in the bottom of the vault, though this is not a necessity.

The operation of the apparatus thus construoted will be readily understood. The air entering at the opening K will be heated by the heater A to any degree desired, and will pass thence through the lower-duct, (1, thereby heating the plate L and the deposits thereon, at the same time absorbing or drying up whatever moisture there may be in the bottom of said duct, and, passing thence up through the opening I into the upper duct, d, will pass back through the same in direct contact with the deposits on the plate L, and from thence into the shaft R, and out through the same into the atmosphere above the roof of the building. By these means I apply air at a much higher temperature and pass it twice through the vault,instead of once, as heretofore, thus greatly hastening the drying or desiccating process.

By taking the air entirely from the exterior of the building, and having the vault entirely disconnected from ventilating ducts or passages of the rooms within the building, I prevent the possibility of the air which enters the vault from penetrating any of the rooms in case of a reversal of the eurrents,or any accident of the kind.

I am aware that a patent has been granted in which there is shown ametal box under the seats of an ordinary privy,with a fire-grate located outside of the same, in which it is proposed to build a fire at intervals for the purpose of drying or consuming the deposits, and that lamps and other appliances have been described as applied to commodes orportable devices for use in dwellings, and therefore I do not claim any of them. Neither do Iclaim a dry closet having a current of air drawn through its vault and out through ashaft; but

What I claim as my invention is- The combination, in a dry closet, of the vault 0, provided with the transverse plate or partit-ion L, with the opening or passage I at one end and the heater A and air-inlet K at the opposite end, the upper portion or duct, d, of said vault being connected to the ventilatingshaft R, all. being constructed and arranged to operate substantially as and for the purpose set forth.
